Abstract
A composite structural panel is formed of a single composite face sheet with a stiffener grid adhesively attached to one side of the face sheet. The stiffener grid if formed of an interlocked set of parallel first elongated grid channels extending in a first direction and parallel second elongated grid channels extending in a second direction. Each grid channel is a hollow channel section including two shear walls formed of a shear wall composite material having woven bidirectional shear wall fiber reinforcement cloth embedded in a shear wall matrix, and a cap extending between the top of each of the two shear walls. The cap is formed of a cap composite material of composite material having unidirectional cap fiber reinforcement embedded in a cap matrix, with the unidirectional cap fiber reinforcement extending parallel to the direction of elongation of the grid channel.
